Continuation of application Serial No. 1229 22, filed October 20, 1902.This application filed July 22,1904.- Serial No. 217,649.

To all whom, it may concern.-

Be it known that 1, CHARLES M. TAYLOR, Jr. a citizen of the UnitedStates, residing at the city of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulSuction Apparatus for Dairy Products, of which the following is aspecification.

The object of the present invention is to provide neat, compact,cleanly, and efficientmeans for separating the unbroken fatty globuleswith or without adherent casein from the free milky portions by theapplication of pneumatics and without fermentation or agitation.

To this and other ends, hereinafter set forth, the invention comprisesthe improvements to be presently described and finally claimed.

The nature, characteristic features, and scope of the invention will bemore fully understood from the following description, takenin connectionwith the annexed drawings, forming part hereof,and in which there isillustrated, principally in central section, an apparatus embodyingfeatures of the invention.

In the drawing, 1 is a cream-chamber, and 2 is a second or vacuumchamber. A housing 3 incloses these chambers, and it is shown as mountedupon legs or supports 4. The base of the housing is shown to slopetoward a discharge-opening 5, provided with a suitable closure 6. Thevacuum or second chamber 2 is provided with a connection, as 7, by meansof which air is exhausted from it by connecting it with any suitabledevice adapted to exhaust air.

a is a lid or cover fitted to the top of the cream-chamber in such a wayas to prevent the access of air.

The exclusion of the outer air to a substantial degree is desirable,because in a place where dairy products abound the air is always more orless infected with bacteria, which induce or promote fermentation, andthe exclusion of air secures greater certainty in the product and agreater degree of uniformity in its condition.

The cream-chamber and the second chamber are separated by a detachableand removable perforated or reticulated plate 8.

9 designates transversely-ranging rods or carriers which support theplate 8.

Super-posed upon the plate 8 is a layer of material 10, permeable by thefluid constitu- I cuts of the cream and im permeable by the fattyconstituents thereof. An example of such a material is blotting-paper orlayers thereof.

It is obvious that with the exception of part 10 the whole apparatus maybe made of metal, and therefore readily cleaned.

In use cream is placed in the compartment 1 and the air-pressure in thechamber 2 is made lower than the air-pressure in the compartment 1.Under these conditions the material 10, being impermeable by the fattyconstituents, retains them upon its upper surface, while the fluidconstituents permeate it, and the effect of the relative difference inair-pressure between the chambers facilitates the removal of the fluidconstituents from the under face of the layer 10, so that they fall fromit into the chamber 2 and may be subsequently withdrawn by aid of theoutlet 5. The fatty constituents are collected from the upper surface ofthe sheet 10 for use. In this way the described action of the sheet 10is promoted and the separation is made with comparative rapidity andwithout opportunity for fermentation and under conditions free fromagitation.

It will be obvious to those skilled in the art to which my inventionappertains that modifications may be made in details without departingfrom the spirit thereof. Hence the invention is not limited further thanthe prior state of the art may require; but,

Having thus described the nature and objects of my invention, what 1claim as new, and desire to secure by Letters Patent, is-

1. Apparatus for making dairy products comprising a housing providedwith acreamchamber and a vacuum-chamber, a perforated support interposedbetween the two, and a layer of material carried by said perforatedsupport and permeable by the watery and impermeable by the fattyconstituents of cream, substantially as described.

2. Means for making a dairy product comprisinga housing provided with acream-chamber and a vacuum-chamber and supports inposed between the twochambers, a perfober below, exhaust connections for the vacu-'um-chamber,a layerof material superposed on said supports and permeableby the Watery adapted to create a lower atmospheric presconstituents andimpermeable by the fatty sure in the second chamber than in the firstconstituents of cream, substantially as dechamber, substantially asdescribed.
